With the AF Configuration Tool on the EOS-1D
X, not only can you select from Case 1 - Case 6,
but three parameters for each can be adjusted
individually.
[Tracking sensitivity] is the parameter that can
be set to track a subject that the AF point had
been following until a different subject (or
background) got in the way.

Selecting -2 results in the targeted subject being
tracked for a longer time before focus changes

An example where
[Responsive: +1/+2] is
effective
When you want to focus on an
athlete who appears suddenly in
the frame.
Example where a skateboarder appeared
suddenly from the far wall. In a situation
like this, setting to [Responsive: +1/+2]
makes it possible to focus even quicker on
the skater that just appeared. (Photo top
